Waste management failures in Juchitán, Oaxaca, have resulted in more than 40 open-air landfills that threaten local public health [1], [2].
This crisis endangers the regional ecosystem and human populations by allowing toxins to seep into groundwater and drainage systems. The lack of a formal disposal infrastructure transforms residential and rural areas into hazardous zones where waste accumulates without oversight.
Reports indicate the number of open-air dumpsites in the Isthmus of Tehuantepec ranges from at least 42 [2] to more than 46 [1]. These sites collectively generate 140 tons of waste every day [1]. The scale of the pollution has reached what specialists describe as critical levels, as the debris contaminates the surrounding environment.
"The problem in the Istmo has escalated to critical levels with more than 46 open-air landfills that generate 140 tons of waste daily," Milenio Hábitat said [1].
The contamination is not limited to the surface. Toxins from the decomposing waste filtrate into the soil and water, creating a long-term health risk for the inhabitants of Juchitán. Local authorities and specialists have identified these sites as primary drivers of environmental degradation in the region.
"The Isthmus of Tehuantepec region, in Oaxaca, is one of those with the highest number of open-air landfills — with at least 42 — causing health effects for human beings," Milenio Hábitat said [2].
“The problem in the Istmo has escalated to critical levels”
The situation in Juchitán reflects a systemic collapse of municipal waste infrastructure. When waste management fails to keep pace with urban growth, the resulting open-air landfills create permanent environmental hazards through leachate, the toxic liquid that drains from landfills, which contaminates aquifers. This creates a public health cycle where the community loses access to clean water while remaining exposed to airborne pollutants and pests.
